FINALIST FOR THE PULITZER PRIZE   For most living Americans, September 11, 2001, is the darkest date in the nation’s history. But what exactly happened on 9/11? Could it have been prevented? And what remains unresolved? Here is the first panoramic, authoritative account of that tragic day—from the first brutal actions of the hijackers to our government’s flawed response; from the untruths told afterward by U.S. officials to the “elephant in the room” of the 9/11 Commission’s report—the clues that point to foreign involvement. New York Times bestselling authors Anthony Summers and Robbyn Swan write with access to thousands of recently released official documents, raw transcripts, fresh interviews, and the perspective that can come only from a decade of research and evaluation. Riveting, revelatory, and thoroughly sourced, The Eleventh Day is updated for this edition—with new reporting on a development that the former cochairman of Congress’s 9/11 probe calls the most important in years.   This is the essential one-volume work, required reading for us all.   “Essential.”—The Wall Street Journal   “Meticulous, comprehensive . . . an extraordinary synthesis.”—John Farmer, 9/11 Commission senior counsel   “This wide-angle look . . . examines the personalities behind the terror plot, U.S. intelligence blunders, the toxic environmental impact on first responders, the march to war, [and] gray areas in the 9/11 Commission Report.”—The Washington Post   “The best available general account of 9/11—soberly written, judiciously weighed, meticulously sourced.”—The Sunday Times
